[sheepdog] [PATCH 00/10] erasure code support, round 4

[Liu Yuan]

This is the final round of erasure coding series. This patch set enables
snapshot/clone/cluster snapshot/ capabilities for erasured vdi and include
previous snapshot tests to work against erasured vdi.

All the tests are passed on my box with './check -ec'

'vdi check' against erasured vdi is left as a future work

Thanks
Yuan
